Environmental Science 1.1-1.2

How could two groups of scientists justify two different conclusions when using the same data?

• Data in science is rarely accurate and should not be used in a scientific argument

• Data is frequently used outside of context to benefit the conclusion scientists want to reach

• Date can be examined in context with other data points in order to draw valid conclusion

• The data is false and needs to be corrected since it can't prove either side of a scientific argument

After performing an experiment, the scientists found unusual results. What should they do next?

• The scientists made a mistake somewhere, but should alter the results to better match his original hypothesis

• Assume the scientists did everything correctly and write up his results to get published in a scientific journal

• Have other scientists replicate his experiment exactly and see if they get the same results

• Change variables in this experiment and repeat it until he gets the data he was expecting

What should a scientist do if they believe another scientists' results are incorrect?

• Replicate the other scientists experiment to see if he gets the same results

• Change variables in the other scientists experiment to tru to change the results

• Research what should likely happen in the experiment from an online resource

• Do a different experiment and show that the results are different

How can you determine if an internet site is reliable?

• The author of the site provides contact information and his or her qualifications

• The author of the site tells you the information is reliable

• The author links to his or her favorite internet sites

• The author states in bold letters that the site was proofread by a librarian

Why would the idea of cold fusion be rejected by the scientific community?

• Cold fusion was a topic that was cited frequently among the scientific community

• The original scientists were unable to attend a science community meeting involving cold fusion to explain their evidence

• Other scientists tried to contact them and they would not answer

• Scientists in the community were unable to replicate the experiment with the same methods and obtain the same results

A scientist read an online article that would be a good basis for an experiment but she is not sure if it is reliable. What should the scientist do?

• Rachel should decide and create a hypothesis based on her research

• Rachel should get the opinion of other scientists upon the validity of the experiment

• Rachel should look for other published scientific journals or articles that provide information relating to this experiment

• Rachel should decide the independent variable for her experiment

What is the most reliable source of information to use in an investigation?

• A magazine found in the school library

• A pamphlet distributed at a local gas station

• A university study found though a google search engine

• Step by step instructions from a blog on social media

Why is it necessary for scientists to compile empirical date before making conclusions?

• Data ensures that scientists are following the scientific method in the proper order

• Data allows scientific theories and laws to form

• Data allows the scientists to gain all credit for experiments taking place

• Data provides evidence to conclude their observations and hypothesis

• Scientists will design their experiment

• Scientist will identify materials needed

• Scientists will analyze their data
